Site description

Duke Energy's Mayo Steam Electric Power Plant began operating in 1983, 11 miles north of Roxboro, North Carolina in Person County. It has a single coal-fired unit that can generate up to 727-MW of electricity per year. The plant is located on Mayo Lake, a popular boating and fishing destination. The company has planned a retirement date of 2029 for the facility, while qualifying that this date is only for planning purposes and could change. There are four units regulated under the CCR rule: CCP Monofill, Ash Basin, FGD Forward Flush Pond and FGD Setting Pond.
